Shoe upper



FIG. 1 is a front perspective view of a shoe upper showing my new design;

FIG. 2 is a side view thereof; and,

FIG. 3 is a rear perspective view thereof.

The broken lines immediately adjacent to the shaded area represent unclaimed boundaries of the design. The broken lines showing the remainder of the shoe are for environmental purposes only and form no part of the claimed design. The difference in shading techniques applied to the wavy stripes represents a contrast of appearance between adjacent stripes and no particular color, material, or finish is claimed. 

CLAIM The ornamental design for a shoe upper, as shown and described.
